Description |
(-)-Securinine is plant-derived alkaloid and also a GABAA receptor antagonist.
|
Target |
GABAA receptor[1]
|
In Vitro |
(-)-Securinine is a major plant-derived alkaloid and also a GABAA receptor antagonist. (-)-Securinine is significantly potent on HeLa cells growth inhibition with IC50 values of 7.02±0.52 μg/mL (32.3 μM). (-)-Securinine induces apoptosis in a dose-dependent manner in the tested cells, increases the percentage of ROS positive cells and depolarized cells as well as stimulates the activity of ERK1/2, caspase-9 and -3/7. (-)-Securinine also induces cell cycle arrest in S phase. Real-time PCR analysis shows high expression of tumor necrosis factor receptor superfamily (TNFRSF) genes in the cells stimulated with (-)-Securinine[1].
|
In Vivo |
In this tumor model, tumor growth is significantly impaired with (-)-Securinine treatment indicating that (-)-Securinine has potential as an Acute Myeloid Leukemia (AML) therapeutic. (-)-Securinine treated mice (n=5 mice, bilateral tumors), exhibit an average of more than 75% smaller tumors than vehicle treated mice at the end of the study period[2].
|
Cell Assay |
The viability of the cells is determined by MTT assay. HeLa cells are seeded in 96-well plates at a density of 5×103 cells/well and treated for 24 h with (-)-Securinine in the concentration range of 1.0 to 20.0 μg/mL. The maximal concentrations of the solvents used in all the MTT experiments are 5.0% (v/v) and 1.0% (v/v) for methanol and DMSO, respectively. The absorption of the obtained formazan solution is measured with a plate reader. The viability results are presented as IC50 mean values of at least three independent experiments[1].

Animal Admin |
6 week old female nude mice are used and injected bilaterally s.c. with 10×106 HL-60 cells. (-)-Securinine treatment is started 10 days after tumor cell injection. Palpable tumors are present for the established tumor model prior to initiating drug treatment. 15 mg/kg of (-)-Securinine or vehicle (30 µL of DMSO and 70 µL of water) are injected i.p. 2 or 3 times a day for 5 days followed by once a day for two days. This injection schedule is repeated for two additional weeks[2].
